PDRN Skincare, Explained: What Salmon DNA Really Does — and Where to Start
PDRN is the salmon-DNA ingredient behind K-beauty's biggest wave. What topical PDRN can and cannot do, and the serums, creams and balms worth trying.
PDRN — polydeoxyribonucleotide — is an ingredient made of purified DNA fragments, classically sourced from salmon, used in cosmetics as a hydrating, skin-revitalizing active that supports the look of elasticity and glow. It reached skincare from an unusual direction: regenerative medicine, and the treatment rooms of Korean dermatology clinics, where injectable PDRN skin boosters — best known under the brand name Rejuran — became one of the most requested procedures in Seoul. The serums and creams now filling K-beauty shelves are the cosmetic translation of that clinic wave: related, but not the same thing. Here is what PDRN actually is, what a cream can honestly deliver, and how to choose from the range.
- •PDRN stands for polydeoxyribonucleotide — purified DNA fragments, classically derived from salmon.
- •Korean dermatology clinics popularized PDRN through injectable skin boosters, best known under the brand name Rejuran.
- •Topical PDRN is cosmetic: it supports hydration and the look of elasticity — it does not do what an in-clinic injection does.
- •PDRN is not always salmon: COSRX blends five PDRN sources and VT Cosmetics uses a vegan, ginseng-derived PDRN.
- •The PDRN range — COSRX, Medicube, VT Cosmetics, Dr.Althea and Eqqualberry — is available in Israel at Skin101.
From wound care to Seoul's clinics
PDRN began its career in medicine, where purified DNA fragments have been used for years in wound-healing therapies. Korean dermatologists then adopted it as an injectable skin booster — the Rejuran treatments that clinics in Seoul run daily for elasticity, fine lines and post-laser recovery, and that people fly to Korea specifically to get. The beauty industry watched that queue form and did what K-beauty does best: it bottled the story. By 2025 PDRN had become the most talked-about ingredient in Korean skincare, repainting entire shelves salmon-pink, and the wave has only widened since.
What a PDRN serum can and cannot do
Honesty first: a cream is not an injection. Clinic results come from delivering PDRN beneath the skin's surface; DNA fragments applied on top are large molecules that mostly stay in the upper layers. What a well-made topical PDRN formula offers is cosmetic — a hydrating, revitalizing layer that supports the skin's bounce, softness and glow, almost always reinforced by partners like peptides, collagen, niacinamide and hyaluronic acid. Used consistently, that is a genuinely pleasing effect, and it is why the category earns its shelf space. But if deeper structural change is the goal, that conversation belongs in a dermatologist's office, not a shopping cart.
The serums: COSRX 5PDRN and Medicube Pink PDRN
COSRX's 5PDRN Collagen line is the most scientific take on the trend: five PDRN types — derived from salmon, centella asiatica, rice, lactobacillus and sea grape — paired with low-molecular collagen and niacinamide. The Intense Vitalizing Serum is the line's core, with hydrogel eye patches and masks built around it for targeted sessions. Medicube's Pink PDRN Peptide Serum is the wave's defining pink bottle — PDRN with five peptides, collagen and niacinamide in a light, fast-absorbing texture — and its matching Pink PDRN Peptide Eye Cream brings the same formula philosophy to the eye area.

Creams, balms and the rest of the shelf
VT Cosmetics — the brand behind Reedle Shot — builds its PDRN line on a vegan route: the PDRN Capsule Cream packs 100,000ppm of PDRN with hyaluronic acid and nine peptides into a plumping moisturizer, while the PDRN Essence Stick Balm, made with ginseng-derived PDRN, is the handbag format — a swipe of essence-balm for eye corners, smile lines and neck, anywhere skin creases before it dries. Eqqualberry gives the trend two personalities of its own — the Aloe PDRN Calming Serum for redness-prone days and the Purple PDRN Pore Minimizing Serum for texture — and Dr.Althea's PDRN Reju 5000 Cream rounds out the range. All of it is available in Israel at Skin101.

Original or fake? How to tell before you buy
The K-beauty boom has a side effect: online marketplaces are full of counterfeit and grey-market products — lookalikes that may be expired, diluted or stored for months in a hot warehouse. Skin101 works with the brands' official importer in Israel, and every product we ship carries the importer's stamp and the official usage instructions on its packaging. That small label is your guarantee of the real formula; if it's missing, you're not buying the original.
Frequently Asked Questions
What is PDRN and where does it come from?+
PDRN — polydeoxyribonucleotide — is made of purified DNA fragments, classically derived from salmon. In cosmetics it works as a hydrating, revitalizing active; some brands now use other sources too, like COSRX's five-source blend or VT Cosmetics' vegan, ginseng-derived PDRN.
Is PDRN skincare the same as Rejuran injections?+
No. Rejuran is an injectable treatment performed in dermatology clinics, delivering PDRN beneath the skin's surface. Topical PDRN serums and creams are cosmetics: they support hydration and the look of elasticity and glow, but they cannot replicate in-clinic results.
Does PDRN skincare actually work?+
As a cosmetic, yes — within honest limits. PDRN formulas are hydrating and revitalizing, and they almost always pair the ingredient with proven partners like peptides, collagen, niacinamide and hyaluronic acid, so consistent use supports bouncier, glowier-looking skin. They do not change skin structure the way clinic procedures do.
Where can I buy PDRN skincare in Israel?+
The PDRN range — COSRX's 5PDRN Collagen line, Medicube's Pink PDRN serum and eye cream, VT Cosmetics' PDRN Capsule Cream and Essence Stick Balm, Dr.Althea's PDRN Reju 5000 Cream and Eqqualberry's PDRN serums — is available in Israel at Skin101 with fast nationwide delivery.
